Safety Comparison

The A6’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 5 Series GT doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Audi A6 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 5 Series GT doesn’t offer height-adjustable seat belts.

Both the A6 and 5 Series GT have child safety locks to prevent children from opening the rear doors. The A6 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The 5 Series GT’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The A6 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 5 Series GT doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the A6 and the 5 Series GT have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, front and rear parking sensors, available crash mitigating brakes, night vision systems, lane departure warning systems, blind spot warning systems and around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the A6 the rating of “Top Pick” for 2017, a rating granted to only 103 vehicles tested by the IIHS. The 5 Series GT has not been tested, yet.

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the A6 has a standard 180-amp alternator. The 5 Series GT’s 170-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2016 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than BMW vehicles. J.D. Power ranks Audi 11th in reliability, above the industry average. With 8 more problems per 100 vehicles, BMW is ranked 14th.

Engine Comparison

As tested in Motor Trend the A6 3.0T 3.0 supercharged V6 is faster than the 535i GT 3.0 turbo 6 cyl.:

Tires and Wheels Comparison

For better traction, the A6’s optional tires are larger than the largest tires available on the 5 Series GT (255/40R19 vs. 245/45R19).

The A6’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the 5 Series GT’s standard 50 series tires. The A6’s optional tires have a lower 35 series profile than the 550i GT’s optional 40 series front tires.

Suspension and Handling Comparison

The A6 3.0T Quattro handles at .95 G’s, while the 535i GT pulls only .87 G’s of cornering force in a Motor Trend skidpad test.

The A6 3.0T Quattro executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the 535i GT (25.1 seconds @ .74 average G’s vs. 26.6 seconds @ .64 average G’s).

For better maneuverability, the A6’s turning circle is 1 foot tighter than the 5 Series GT’s (39 feet vs. 40 feet). The A6’s turning circle is 2 feet tighter than the 5 Series GT xDrive’s (39 feet vs. 41 feet).

Chassis Comparison

The Audi A6 may be more efficient, handle and accelerate better because it weighs about 650 to 700 pounds less than the BMW 5 Series GT.

The design of the Audi A6 amounts to more than styling. The A6 has an aerodynamic coefficient of drag of .28 Cd. That is lower than the 5 Series GT (.3 to .32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the A6 get better fuel mileage.

Cargo Capacity Comparison

With its sedan body style, locking rear seatbacks and remote trunk release lockout, the A6 offers cargo security. The 5 Series GT’s hatchback body style and non-lockable folding seat defeat cargo security.

Ergonomics Comparison

The A6’s available rear sunshade is power operated, allowing the driver to remotely raise and lower it. The sunshade available in the 5 Series GT is manual, and has to be raised or lowered in the rear.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the A6 is less expensive to operate than the 5 Series GT because typical repairs cost much less on the A6 than the 5 Series GT, including $230 less for a water pump, $224 less for an alternator, $28 less for front brake pads, $306 less for fuel injection, $154 less for front struts, $1027 less for a timing belt/chain and $523 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Audi A6 will be $16719 to $17117 less than for the BMW 5 Series GT.
